Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 557

*OPC?

Sets bit 0 in the standard event status register to “1” when pending operations have

finished. It does not hold off subsequent operations.

The *OPC? query stops new commands from being processed until the current processing

is complete. Then it returns a “1”, and the program continues. This query can be used to

synchronize events of other instruments on the external bus.

The instrument does not wait for completion of all processes for these commands. The

processes that are monitored are identified in the STATus:OPERation register. These

include:

For example, if you want to verify the completion of both calibration and waiting for trigger

set :STAT:OPER:ENAB 33 and monitor any changes.

Key Type: There is no equivalent front-panel key.
